I have a BTU Reflow 8 stage (PCDIU software) oven. The max temp. that it will allow is 270 degrees. I am trying to use a High Temp solder paste and the profile states that I must go between 260 and 270 degrees. My question is, is there a way to incre

A slow profile should get you up to temp unless you have severe mass on your board. 8 zones is a lot oven to work with. There are no lead services that can run your board for you. Might be expensive, but use this cost to justify a real high temp

I don't know of any articles but you will see the following problems: The flux will evaporate from the paste and your solder joint will look very grainy or will not reflow at all. The paste will not have a good, tacky quality. Your pick and place

Bill, We only allow 3 boards to be printed in front of the pick and place equipment. It is important to keep the abandon time to a minimum. You did not mention the paste that you use. Do you use no-clean or water soluble? Do you use lead free?

Hello, I have an oven with a big fail. The Control Unit. It is a 5 zones oven (BTU VIP70)and has more than 10 years, and I think that now is not interesting to repair. I think to buy an offer, an oven Heller of 7 zones + cool,(better for lead free).

It really depends on what deliverables BTU can offer and successfully accomplish without the complexity of various reinvention activities. The basis of its� vehicle stability as a total platform should be broken into a framework of goals and objecti

Hi All, I have vendors and even customers telling me that to properly run RoHS compliant products I should have ovens with more zones than my Heller 1500's. I have been running RoHS compliant product with these with very good results. So what ar

G, it is called, "I just went to a sales seminar on pbfree" Show them your profile and call them to the table. Make them tell you specifically what is wrong with your profiles. and even better yet make them explain to you why the extra zones are

What we've seen is more heated length gives you the ability to run the oven at a higher chain speed. Notice, heated length... not # of zones. Needing to achieve higher temps at reflow can cause you to have to reduce your chain speed. For l
